How's your food? You eating enough to support that amount of running?

Take a nap if you can. I find when I hit a new mileage level for several weeks the fatigue builds. Sleep is needed. Then I adjust. It doesnt mean you will always need more sleep at 40 mpw, but that this go round you may. The kind of exhausted I get when I am increasing my training level often is served well with a 10 minute cat nap.
I also have had good luck when I am exhausted in the middle of a program to look at the timing of my food. Not the overall quantity, but am I eating the right stuff at the right time. Same with watching the caffeine. Scaling back on the caffeine at certain times has given me more overall energy - probably from higher quality sleep.
But any time I am pushing myself my sleep needs increase. Just this week I think I napped 2 or 3 times. One real nap, 2 10 minute naps.
And run earlier...as early as you can. I know you usually go when Dane is in school, so try to go as soon as he goes instead of putting it off. Matching your running to natural energy cycles in the day can help ALOT with overall energy and fatigue. I feel sleepy all morning if I havent run yet.
I get night cramps when I have too much potassium in my system. A day or two without the post run banana usually clears that up. You can have all the salt in the world in your system, but too much potassium can cause problems. The only reason I know of this one is because I had a friend years ago that had terrible leg cramps while sleeping. He went to the doc, and the doc told him to quit eating bananas. The cramps stopped. So when i get leg cramps at night, I skip the bananas, and the cramps stop..
